Co-located Device Group Content Delivery via Acoustic Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content delivery systems struggle to effectively present targeted content to users across multiple devices in proximity, particularly when one device has enhanced presentation capabilities, such as a large screen, while others have limited display capabilities, like smartphones.
Innovation Solution
A method and system that identify co-located devices, determine events on these devices, and store information related to these events in a log, allowing for the selection and presentation of content on devices with enhanced capabilities based on aggregated user data and event records, optimizing content delivery to reach a larger audience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If content is delivered to multiple co-located devices, then content reach and audience coverage is improved, but device complexity and system coordination requirements increase
Solution Approach 1:
The patent combines multiple co-located devices into a unified group identified by a common group identifier. Devices detect each other's presence through acoustic signals (sub/super/audible tones) and form a coordinated group, allowing content to be delivered to multiple devices simultaneously while managing complexity through unified group management rather than individual device coordination.
Solution Approach 2:
The patent introduces an intermediary system that receives events from one device, evaluates follow-on opportunities, and coordinates content delivery across the co-located device group. This intermediary approach manages the complexity of multi-device coordination by centralizing the decision-making logic for content selection and timing.
2Reliability
If content is selected based on aggregated events from co-located devices, then content relevance and user engagement are improved, but information processing requirements increase
Solution Approach 1:
The patent performs preliminary actions by detecting device presence and forming co-located groups in advance, before content delivery decisions are made. By pre-establishing the group structure and identifiers, the system reduces processing requirements during actual content selection, as the framework for aggregated event processing is already in place.
3Productivity
If events from co-located devices are monitored and logged, then follow-on content opportunities are improved, but data storage and retrieval requirements increase
Solution Approach 1:
The patent creates a universal event log structure that serves multiple purposes: storing events from any device in the co-located group, enabling follow-on opportunity evaluation, and providing data for content selection. This multi-functional log reduces the need for separate storage systems for each device or event type, optimizing data storage efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the presentation of content on devices with enhanced capabilities, such as large screens, while also considering user interactions and preferences from co-located devices, improving content relevance and engagement by targeting a broader audience.
Implementation Method 1
detecting, by one of the first device or the second different device, a presence of another device based on sub, super or audible tones generated by the other device
Data Source
AI summary
Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. A first device associated with a first user is identified. A second different device, associated with a second different user, is determined to be in proximity to the first device, forming a first group. A determination is made of an occurrence of an event in association with the second different device. The event is evaluated to determine when the event is indicative of a follow-on opportunity for presentation of content to the first user. The information related to the event is stored as a record in a log in association with an identifier for the group. A first opportunity to provide content to the first device is identified and evaluated including locating the record. Information in the record is used when selecting content for delivery in response to the first opportunity.
